The new app lets you choose a license for your photos, profile text, and status updates, as well as any video content you've uploaded. Each media, such as every photo you've posted, must fall under one license, so right now it's an all-or-nothing choice. (The folks at Creative Commons hope this could change in the future.) The Creative Commons site has a description of all six main licenses to help you understand what makes sense for your content. Once you answer a few basic questions—such as whether to grant commercial use of your work—the application will automatically select the appropriate one for you.

We're not entirely convinced that this app will help Facebook or others adhere to your rights as you define them, but perhaps seeing a license alongside your content may cause them to think twice before appropriating your work.
